In recent years there has been rapid improvement in text-to-speech (TTS) technology due to the widespread adoption of neural network based acoustic models [1]}, [2]} and vocoders [3]}, [4]}, [5]}; Subsequently, it is now possible to convincingly use synthetic speech to replace some content in place, as it can potentially match the original speech in terms of clarity, speaker similarity, and prosody. We refer to this line of research as text-based voice editing (TBVE).
